Abstract：Aiming at a T-shape structure formed by a lateral plate and an additional plate, the theoretical analysis of vibration attenuation characteristics is executed. Using the finite element method, the rules of the additional plate’s various parameters versus structural vibration suppression and transfer attenuation are systematically studied. Based on these conclusions, the oil baffle of an oil pan is modified. The research results show that, compared with other structural parameters of the oil baffle, the plate thickness can more significantly decrease the amplitude of local area and weaken the transfer of vibration. Moreover, double-layer additional plate has the same change trend of vibration suppression and transfer attenuation with plate thickness’s addition, but has better characteristics.
